hi thanks for response
when i enter this as root
smb96 wrote:/etc/init.d/acpid start
it says that acpid is alredy started
shows my only that Fn+F1 (which is not marked as fn key )is working and Fn+Esc and Fn+F3 is working
shows same that the same and other keys are "active" with Fn combination
think that's not bad, but the brightness keys with fn are not showing any reaction
this for now i will look now the link that you have posted and write again if this works
echo 60 | sudo dd of=/proc/acpi/video/VGA/LCD/brightness
change setting in file brightness only but there is no reaction in brightness
to menu.lst seams to not working neither
didn't try using smartdimmer because is not it's not installed (no package in repo to install )
but looks that smartdimmer is a part of powermizer on nvidia.
when i open nvidia x serwer settings i see that this powermizer is an works
any other idea ?
